Vettel got ahead of team-mate Kimi Raikkonen who started on pole to secure victory in Monte Carlo as Lewis Hamilton managed to finish seventh having started back in 13th.

Jenson Button, in in place of Fernando Alonso who is racing in the Indy 500 later todayt, was forced to retire after a collision with Pascal Wehrlein.

It was Vettel's third win of the season and extends his lead in the Driver's Championship to 25 points and Ferrari's first 1-2 since 2010.

Championship leader Vettel trailed pole-sitter Kimi Raikkonen for the opening phase of the race, but emerged from his one and only pit stop ahead of his Ferrari team-mate after stopping later.

Button, back in Formula One as a one-off replacement for Fernando Alonso, was involved in a hair-raising accident after he flipped Pascal Wehrlein's Sauber following an adventurous overtake in the closing stages of the race.

Wehrlein's car was resting precariously on its side on the entrance to the tunnel and the German was trapped in his seat.

The safety car was deployed, and when Wehrlein's car was rolled back on to its four wheels by the marshals, the 22-year-old mercifully emerged without any obvious injury. He walked away from his cockpit and was taken to the on-track medical centre for precautionary checks.

Button, in what is likely to be his last race, retired having sustained significant damage to the front left of his McLaren following the crash.

The race resumed six laps after the extraordinary incident, but Daniel Ricciardo, despite kissing the barriers at turn one, held off Valtteri Bottas and Max Verstappen to take the final spot on the podium, while Hamilton was unable to do anything about Carlos Sainz as he crossed the line in a lowly seventh place.
